unity IndexOutOfRangeのエラーが出る

ゲームを再生していたところ，プレー途中で以下のようなエラーが得られました．
配列の定義域外を参照したことによるエラーであることは経験則から理解しましたが，該当の配列がおそらくデフォルトで存在しているものであると考えています．
unityの仕様について詳しくないのでこれらのエラーコードが意味しているところや原因，対処がわかりません

UnityEditor のエラーなので Unity 側の問題かもしれません。
恐らく下記の箇所で無効なインデックスにアクセスしてエラーになっているものと思われます。
https://github.com/Unity-Technologies/UnityCsReference/blob/2020.3/Editor/Mono/GUI/ListViewShared.cs#L250

事象が再現するようであればバグ報告か Unity Forum で質問（要英語）してみると良いかもしれません。
